In Celestia's Year of 678 a new group of the Equestrian Royal Guard has come up with a new division: The Royal Equestrian Inter-dimensional Exploratory Corps. Sadly things go awry as the majority of the members are slaughtered and only one thing remains. Sadly it is has very little of what we call a free will, it is a Pony Information Recording Golem (Patent Pending). It is influenced by those in Equestria but before it can complete its mission, it runs across a man who calls himself a, "Devil Dog."
